Stage 9 was a non-commercial, virtual reality recreation of Star Trek The Next Generation's Enterprise starship. It allowed fans of the series to explore the beloved vessel and immerse themselves in the chief setting of the series. It was built over the past two years using Unreal Engine 4 by fans who have taken great pains to state that the project was not affiliated or licensed with CBS or Paramount and that they weren't doing this to make money, only to artistically demonstrate their fandom. That did not stop CBS from sending a cease and desist letter, thus shutting down the project as CBS was reportedly unwilling to engage in dialog.

There are some projects for collaborative sci-fi canon. I think Orion's Arm [orionsarm.com] might be the one somebody here linked a while back that was fairly polished.
I also came across Terran Shift [lostluggagestudios.com] looking for Orion's Arm again, but it looks like all they've developed is a future history.
